I was looking for a replacement mains adapter for a Pure Evoke-1 radio, an early model which needs a 12V mains adapter. The information provided for this adapter suggests it is suitable, but on receipt I found the connector looks very similar but does not make good contact in the back of the radio, so the radio only operates intermittently when you hold the connector at the right angle - clearly unacceptable. As I am an electrical engineer I swapped the new connector for the old one, and it works fine. However note that swapping the connectors is not that simple, and you need to check carefully that the connector is connected the right way round so that the +12V is on the centre of the connector. You can't rely on the stripe and plain markings on the cable - I found they had to be swapped to get the right polarity of connector. If you are looking for a replacement adapter for a Pure Evoke-1, bear in mind it may not work unless you have the skills and equipment to swap the connector.
